摘要:

AbstractThe synthesis of 6‐dehydro‐9β, 10α‐progesterone (IV) from progesteroneviairradiation of 3,20‐bis(ethylenedioxy)pregna‐5,7‐diene (II) is described. An analogous synthesis has been accomplishedvia3‐(ethylenedioxy)pregna‐5,7‐dien‐20‐one (VI).Pyrolysis of the 9,10‐seco‐bisacetal (IX), a vitamin D analogue, followed by hydrolysis and isomerization, gave the 8α,10α‐isome
